Force and torque on loops physics question. Please show work.
A small current loop of area A = 0.001 m 2 and moment of inertia I = 7e-07 kgm 2 carries a current i = 0.0042 A with its magnetic moment perpendicular to the Earth's magnetic field. The magnitude of the Earth's fild is B = 4.2e-05 T. Draw a diagram with dF (infinitesimal force) at the four min and max points, two where current is parallel to B, and two where current is perpendicular to B. *find the net torque in the correct directions * proof for the direction of rotation What is the magnitude of the net torque T on the loop? T = Nm If the Earth's magnetic field points north and the loop's magnetic moment points west, the loop would rotate clockwise as seen from the north looking south the south looking north above looking down below looking up What is the angular acceleration a of the loop? a = rad/s 2
